FEZZ Luna EVO is an integrated vaccum tube amplifier that is based on EL34 pentodes working in a push-pull configuration. It is both an extremely interesting and important design as well, especially when viewed in a broader context. This amplifier – introduced last (2025) year – replaces the well-known and popular Silver Luna model that was actually the first product from Fezz Audio. Moreover, according to the manufacturer, the new Luna is an amplifier that is devised entirely from the ground-up. Of course, some of the original concepts and well-proven ideas have remained in the new design. I am referring, for example, to the use of EL34 tubes in the power stage or the use of proprietary output transformers based on toroidal cores.
Nevertheless, the changes in the new model are significant enough that we are actually dealing with a completely new thing here. At the same time, the new Luna is also an amplifier that is supposed to offer a modern and even more refined version of tube technology in a truly user-friendly form. It is also supposed to provide significantly better sound than its predecessor by the virtue of several design solutions that are important from the sonic perspective. In other words, if we are to believe the manufacturer’s assurances, it has approached the new model, which refers to the moon in its name, with great reverence. This is not surprising, as Luna replaces Silver Luna, the model that – many years ago – started it all.
Before we move on, let us go back in time a little and look closer at a certain context, including the historical one. Because this context is of extreme importance, especially when looking at the new model that is the subject of the review here. FEZZ is a domestic and family-owned brand, which was established on the basis of company called Toroidy.pl. The latter manufacturer is, in turn, very well known in the audio industry. And not only on our local market, but also – and perhaps above all – beyond our borders. The reason for this is very simple indeed – the company from Białystok makes very good toroidal transformers dedicated for use in audio equipment. They are good enough (and often made to exact specifications, in special shielded versions) that they can often be found in very expensive and very recognisable, renowned hi-end apparatus.
Moving on to the FEZZ brand itself (whose name, by the way, has changed from “Fezz Audio” to “FEZZ” in 2022), the premiere of its first product took place over 10 years ago. It was the Silver Luna integrated amplifier, which was officially unveiled at the Warsaw’s Audio Video Show in 2015. Those were the days when Chinese tube amplifiers, whose workmanship at the time left much to be desired, ruled almost unchallenged here in our country. And then suddenly, out of the blue, a Polish manufacturer “jumped in” with an amplifier that was not only reasonably priced, but also really well-made. To make things even more interesting, it was also quite capable sonically. In 2016, Polish manufacturer presented another not-so-solid-state amplifier. This time it was the Titania model based on KT88 power tetrodes.
Just a bit later things got really interesting, because in 2018, not only did the Omega Lupi headphone amplifier appear on the market, but also the Mira Ceti model based on Single-Ended topology and the venerable 300B tubes. In addition, in 2019, Fezz Audio introduced a 2A3 tube-based version of the Mira Ceti and, also in the same year, a whole line of phono preamplifiers (Gaia Mini, Gaia, Gratia). Another extremely interesting design was introduced a year later, 2020 to be exact. It was the Lybra 300B model, which was still based on Single-Ended topology, but now using two 300B tubes per channel operating in parallel. And thus providing quite generous power capability, not to mention that at the same time Fezz Audio embarked on that not-so-long list of manufacturers offering PSE (Parallel Single-Ended) versions of their amplifiers.
Yet it was the 2022 that was a major breakthrough for the Polish brand. It was that year when the EVO line of devices saw the light of the day. They were the result of cooperation with the KABO&PYDO design studio and visually set things really apart. The EVO series initially offered several models of tube amplifiers and three models of preamplifiers (all mentioned above, in EVO versions). Shortly afterwards, the first Equinox DAC digital-to-analogue converter – designed in collaboration with the famous Lampizator brand – was introduced.
In 2024, the Sagita and Sagita Prestige tube preamplifiers were launched. I could go on and on hehe, but let me just point out one thing. You don’t have to be an expert on the audio market to notice that the company from Białystok has come a long way and become a globally recognised brand. A great and palpable confirmation of this can be the recently introduced Magnetar and Supernova series that really sets the bar high. At the same time, the new Luna that we have on our hands here is no less important.
